As my first question can be answered implicitly, I put some more:

Independently of how a list of IP addresses is gathered, is there any
reason not to publish it?

Is there any reason why postmasters would not want to say what DNSBLs
their servers look up and what decisions they make thereafter? If I knew
my message were to be rejected, I would abort sending tout-court,
irrespective of my hat's color. Would that be a disadvantage for the
target host?


Publishing the list of RBLs that I use would allow spammers to target my servers more effectively, and more efficiently. Each spambot that they controlled could look up my list, and determine whether they could reach me. Spambots can now simply target their mail at servers that are likely to accept it.
